[Pathological intestinal findings: case related differential diagnosis and investigations].

Transabdominal ultrasound is the most commonly performed initial examination for intestinal diseases and due to its high availability and the absence of side effects from ionic radiation, it is ideal for serial examinations. New techniques such as tissue harmonic imaging combined with the use of contrast media appear to increase the diagnostic accuracy. For diverticulitis, infectious colitis and intestinal tumours, there is as yet a lack of data. Using typical case examples, the ultrasonographic features of important intestinal conditions are demonstrated.
